Genes affected

OTOF (HGNC:8515): (otoferlin) Mutations in this gene are a cause of neurosensory nonsyndromic recessive deafness, DFNB9. The short form of the encoded protein has 3 C2 domains, a single carboxy-terminal transmembrane domain found also in the C. elegans spermatogenesis factor FER-1 and human dysferlin, while the long form has 6 C2 domains. The homology suggests that this protein may be involved in vesicle membrane fusion. Several transcript variants encoding multiple isoforms have been found for this gene.

The Ile1405Val variant in OTOF has not been previously reported in individuals w ith hearing loss, but has been identified in 1/196 (0.5%) of Italian chromosomes by the 1000 Genomes Project (http://evs.gs.washington.edu; dbSNP rs201123430). Computational prediction tools and conservation analyses do not provide strong support for or against an impact to the protein. In summary, additional informat ion is needed to fully assess the clinical significance of this variant. -
